If you've been shopping for sustainable clothing, you've likely encountered the term TENCEL Lyocell. But what exactly is it — and why are Europe's most respected sustainable brands, including Portugal's Impetus, choosing it over conventional cotton?
What Is TENCEL Lyocell?
TENCEL Lyocell is a natural fibre made primarily from sustainably sourced wood pulp — usually eucalyptus trees. The production process is closed-loop, meaning the water and solvents used in manufacturing are recycled back into the process, producing minimal waste.
The result is a fibre that is softer than silk, cooler than cotton, naturally antibacterial, and produced with a fraction of the environmental impact of conventional textile manufacturing.
TENCEL vs Cotton — Key Differences
Cotton requires enormous amounts of water to grow — approximately 10,000 litres per kilogram of fabric. TENCEL Lyocell uses up to 80% less water. Cotton also frequently relies on pesticides and fertilisers. Eucalyptus for TENCEL grows rapidly with minimal inputs and is harvested from sustainably managed forests.
From a wear perspective, TENCEL is naturally temperature-regulating, moisture-wicking, and hypoallergenic — making it ideal for intimates, sleepwear, and everyday essentials that sit directly against the skin.
